Description

Deep-sea fisheries are an often unnoticed but critical part of the global food system. These fisheries, located at depths typically greater than 200 meters, contribute to the supply of seafood, which is a vital source of nutrition for millions of people around the world. As the global population continues to grow and the demand for sustainable sources of food increases, deep-sea fisheries offer potential as resilient bioeconomic systems that can support food and nutrition security while promoting sustainable development.

The vast depths of the ocean are home to a diverse array of species, many of which are of high commercial value. Species such as orange roughy, grenadiers and various species of deepsea shrimp are harvested in significant quantities to meet global seafood demand. These fisheries play a key role in ensuring food security by providing protein-rich food sources that are essential to the diets of many communities. Seafood, including that from deep-sea fisheries, is rich in omega-3 fatty acids, essential vitamins and minerals, making it an important component of a balanced diet. However, managing deep-sea fisheries presents unique challenges. The ecosystems that support these fisheries are often brittle, with species that grow slowly, mature late and have low reproductive rates. This makes them particularly vulnerable to overfishing and environmental degradation. Unsustainable fishing practices, such as bottom trawling, can cause significant damage to deep-sea habitats, leading to longterm ecological impacts that threaten the very species that these fisheries rely upon. In this context, ensuring the sustainability of deep-sea fisheries is utmost if they are to continue to contribute to food and nutrition security in the long term.

To address these challenges, a bioeconomic approach is essential. Bioeconomics combines ecological and economic principles to ensure that the exploitation of natural resources, such as deepsea fish stocks, is conducted in a manner that is both ecologically sustainable and economically viable. This involves setting catch limits that take into account the slow growth rates and reproductive patterns of deep-sea species, implementing monitoring and enforcement mechanisms to prevent illegal fishing and promoting fishing practices that minimize damage to the ocean floor and other habitats. A resilient bioeconomic system is one that can adapt to changing environmental and economic conditions while maintaining the capacity to provide food and livelihoods. Deep-sea fisheries, when managed sustainably, have the potential to be such a system. They can provide a steady source of income for fishing communities, contribute to global food supplies and promote the sustainable use of marine resources. This is particularly important in the context of climate change, which is altering ocean temperatures, currents and the distribution of marine species. The resilience of deep-sea fisheries to these changes depends on effective management practices that protect fish stocks and the ecosystems that support them.

Sustainable deep-sea fisheries also have a role to play in achieving the United Nations’ Sustainable Development Goals (SDGs), particularly Goal 14, which focuses on conserving and sustainably using the oceans, seas and marine resources. By promoting responsible fishing practices, reducing bycatch and protecting vulnerable marine ecosystems, deep-sea fisheries can contribute to the long-term health of the oceans while ensuring that marine resources are available for future generations. Additionally, by providing a sustainable source of protein and other nutrients, these fisheries support efforts to end hunger (SDG 2) and improve health and well-being (SDG 3). One of the key aspects of achieving sustainable development through deepsea fisheries is international cooperation. Many deep-sea fish stocks are found in areas beyond national jurisdiction, requiring countries to work together to manage these shared resources effectively. Regional Fisheries Management Organizations (RFMOs) play an essential role in coordinating the management of deep-sea fisheries, setting quotas and enforcing regulations that aim to prevent overfishing and protect marine biodiversity. Effective governance at both the national and international levels is essential for ensuring that deep-sea fisheries remain viable and resilient.

Innovation and technological advancements also have a role to play in making deep-sea fisheries more sustainable. Improvements in fishing gear can reduce the impact of fishing on the seafloor and limit bycatch, while satellite monitoring and data analytics can improve the accuracy of stock assessments and help ensure compliance with fishing regulations. These tools, when combined with traditional knowledge and community-based management practices, can help create more resilient and sustainable deep-sea fisheries.
